0 the existence of the same chemical substance in more than one form, each with different physical qualities -- 同素異形（現象）
He also examined the phenomenon of allotropy, in which the arrangements of the same atoms, such as carbon, give different forms, such as graphite or diamond, which exhibit different qualities.
Polymorphism can potentially be found in many crystalline materials including polymers, minerals, and metals, and is related to allotropy, which refers to elemental solids.
For pure chemical elements, polymorphism is known as allotropy.
He also introduced the possibility of allotropy in chemical elements when he discovered that diamond is a crystalline form of carbon.
The term "allotropy" is used for elements only, not for compounds.
This rearrangement, called allotropy or polymorphism, may occur several times, at many different temperatures for a particular metal.
Polymorphism can potentially be found in any crystalline material including polymers, minerals, and metals, and is related to allotropy, which refers to chemical elements.
